Answer

Bonjour Aashpreet,
This is an excellent question! 
It all comes down to the verb: is it transitive or intransitive?
A transitive verb is a verb which requires one or more objects -> use avoir in Le Passé Composé

Ils ont convenu d'un rendez-vous = They agreed to a meeting
Mes parents ont subvenu à mes besoins = My parents provided for me.

An intransitive verb is a verb which does not require an object (including "venir")-> use être in Le Passé Composé

Les problèmes sont survenus soudainement = The problems happened suddenly
Marie est venue hier = Marie came yesterday

Attention : some verbs can be both - and, therefore, can use être or avoir.

Je suis parvenu(e) à la joindre = I managed to get hold of her
Il a parvenu à chanter = He managed to sing

There are several excellent free online conjugation sites. Berscherelle is another comprehensive and classic site, covering both “standard” and rectified spelling, and includes pronominal verbs as separated listings.

Answer

"Parvenir" goes with être and "Convenir" goes with avoir (unlike venir)?? Same goes with "Survenir" (goes with être) and "Subvenir" (goes with avoir). Where can I find all such cases of Venir???

The conjugation tables you have shared above does not have these verbs.
